	Packet Probe register Opcode is a 4-bit register that selects candidate packets based on packet opcodes (0 disables the filter):

Module Instance	Base Address	Register Address
`i_noc_ccu_ios_probe_emac_main_Probe`	`0xFFD22800`	`0xFFD2289C`

Size: 32

Offset: 0x9C

Access: RW

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
